The subfamily Cremastinae Förster, 1869 (Hymenoptera: Received: Ichneumonidae) was studied in Fars and Hormozgan provinces (southern 13 December 2015 Iran). The specimens were collected using Malaise traps and sweeping nets. Accepted: Nine species were identified of which two species including Temelucha afghana 03 January 2016 Šedivý, 1968 and Temelucha confluens (Gravenhorst, 1829) are new records for Published: the fauna of Iran. With result of this study, the number of Cremastinae species 03 January 2016 known from Iran has increased to 24 species in six genera. An identification Subject Editor: key to Iranian Cremastinae is provided, as well as a morphological diagnosis Samira Farahani for the newly recorded species.

They are koinobiont endoparasitoids, but the final instar larva The subfamily Cremastinae comprises emerges from the host and completes more than 750 described species feeding externally and almost consuming worldwide (Yu et al. 2012). The members of everything except the head capsule of the Cremastinae occur mainly in the arid host (Quicke 2015). The biology of some regions (Gauld 1984; Dasch 1979; Townes species of Cremastus Gravenhorst 1829 and 1965;). The Cremastinae are well known as Pristomerus Curtis 1836, which are important biological control agents of leaf- associated with codling moth, Cydia rollers, gall-makers, wood-borers and other pomonella (Linnaeus, 1758) (Lepidoptera: concealed living insect-larvae (Narolsky Tortricidae) were studied by Bradley and 2002). Most species are parasitoids of Burgess (1934). Hosts of Pristomerus are weakly concealed Lepidoptera, but at least Lepidoptera families such as Tortricidae, some of them attacking immature stages of Crambidae, Sesiidae and Oecophoridae Coleoptera in similar habitats (Townes Corresponding author: Ali Asghar Talebi, E-mail: [email protected] Copyright © 2015, Amiri et al.

Cremastinae of Iran have version 1.04. The specimens are deposited recently been investigated by several in the Collection of Department of researchers (Narolsky and Schönitzer 2003; Entomology, Tarbiat Modares University Kolarov and Ghahari 2005; Masnadi- (TMUC), Tehran, Iran. In the species list, Yazdinejad and Jussila 2009; Kishani the following data are included: valid taxa Farahani et al. 2010; Ghahari et al. 2010; names, synonyms, published records with Ghahari and Jussila 2010a, b, 2011a, b, c, d; provincial distribution in Iran and other Ghahari and Schwarz 2011; Barahoei et al. chorological data. Classification and the 2014; Sarafi et al. 2015) mainly in the north distributional data followed Yu et al. (2012). and northwest of Iran. The objective of this Some abbreviation used in redescription study as a part of our research is the survey new record species are as follows: OOL of Cremastinae fauna of some southern (Ocular ocellar line) = distance between regions of Iran. The results may be useful for future biological control of insect pests lateral ocellus and compound eye margin; and the ecological studies. POL (Posterior ocellar line) = distance between inner margins of the posterior Materials and Methods ocelli. Sampling was performed using Malaise Results traps and sweeping net at 22 locations in Fars and Hormozgan provinces from The results of this study and review of the February 2011 till August 2013. Different previously recorded taxa revealed the ecosystems such as forests, rangelands, existence of 24 species of Cremastinae desert plants and mangrove, fruit orchards belong to six genera in Iran, of them two (tropical and non-tropical trees) and agro- species including Temelucha afghana Šedivý, ecosystems were selected for sampling. The 1968 and T. confluens (Gravenhorst, 1829) captured specimens were extracted from are newly recorded for the Iranian fauna. the collecting jars irregularly with one or two week intervals, then treated with Key to the genera and species of Iranian mixture of ethanol (60%) /Xylene (40%) for Cremastinae two days, followed by Amyl acetate for two days (AXA) and finally placed on the 1.
